Ermaf direct air heaters have the advantage of very high efficiency and short warm-up times. Thanks to the reliability and high quality of their components, these direct air heaters operate for more than 40 years with minimal maintenance.

GP heaters now not only provide more features and higher reliability, but are also more user-friendly in terms of installation and operation. They are also easier to maintain and clean.

All control of the ACU is much easier and faster. Everything is more intuitive than ever before. The user interface has improved features: status indication, flame signal, error monitoring and many more. Thanks to the waterproof housing, the control unit together with the gas valve is even better protected from water and dust. The gas inlet is now located at the bottom for easier pipe connection.

Improved hygienic design with smooth surfaces
Short-circuit proof; no internal fuse needing manufacturer's repair

Stainless steel nozzle on GP40/70 delivers superior corrosion resistance
Highest safety class and best performance
